LOCK AND SEAL.

7. '0 all 1015077021 may concern:

Be it known that I, Poems WV. FUNs'roN, a citizen of the United States,residing at Carlyle, in the county of Allen and State of Kansas, haveinvented certain new and useful Improvements in Locks and Seals; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to new and useful improvementsin locks and sealsand has for its primary object the provision of means adapted to fastena door in a closed position and which cannot be opened without breakingthe seal. thereby providing a device es pecially adaptable for sealingrailway cars and other vehicles.

Another object of this invention is the provision of a bolt adapted toreceive an endless seal and extends into a keeper and held againstretraction until its end is movedbeyond the keeper which destroys ormutilates the seal, indicating that the bolt has been retracted ortampered with.

A further object of this invention is the provision of a lock and sealof the above stated character which may be easily and quickly operatedand which will be simple, durable and efficient, and which may bemanufactured and sold at a comparatively low cost.

lVith these and other objects in view as will become more apparent asthe description proceeds. the invention consists in certain novelfeatures of construction, combi nation. and arrangement of parts as willbe hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had tothe following description and accompanying drawing, in which Figure 1 isa view illustrating a lock and seal constructed in accordance with myinvention applied to a door frame.

Figure 2 is an enlarged side elevation illustrating the same with thebolt in an unlocked or retracted position,

Figure 3 is a. sectional view illustrating the device with the bolt in alocked position.

Figure 4 is a similar View illustrating the bolt moved into a positionready to be re Specification of Letters Patent.

Figure 5 is a detail view taken on line 55 of Figure 3, I

Figure 6 is a. fragmentary perspective view of the locking end of thebolt.

Figure 7 is a perspective view of the seal.

Referring; in detail to the drawings, the numeral 1 indicates a baseadapted to be secured to a door frame 2 by suitable fasteningelements 3and said base has secured thereto a. casing: 4L by means of cars 5 thatrest on the base 1 and are secured thereto by rivets or like fasteners6. The end walls of the casing 4 have alining openings 7 to slidablyreceive a lOClCiIig bolt 8. one end of which h s detachably securedthereto a handle 9. The handle 9 is preferably secured to the lockingbolt 8 by means of a pin 10 extending through said handle and bolt andwhich may be headed so as to prevent the removal o'l" the handle 9 by anunauthorized person. The other end or the locking end of the bolt 8 hasa slot 11 which opens outwardly through said end of: the belt for thepurpose of receivinga seal The seal 12 is of. endless formation andconstructed from comparatively thin metal: A rib 13 is also formed onthe locking end of the bolt adjacent the slot 11. A. substantiallyU-shaped locking spring 1% is secured to the base 1 within the casingtby fasteninn elements 15 and has its ends disposed in engagement withthe bolt 8 and said spring is slightly under tension by being inengagement with the bolt. A locking: notch 16 is formed in the bolt 8within the casing: and has a straight shoulder 17 adapted to be engagedby one nd of the spring M to pre ent the bolt from being' retracted whensaid bolt is in one position. The bolt is free for sliding movement inthe casing -lwhen the notch is disengaged from the spring 141- byturning the bolt 8 within the casino by the handle.

A keeper 18 is formed on one end of the base 1 and is provided with acircular opening 21 to receive the locking end of the bolt 8. A hasp 20is connected to the door 2 and is adapted to be placed over the keeperprior to inserting the bolt therein. Radially eX- tending slots ornotches 22 and 23 are formed in the keeper 18 and communicate with thecircular opening 21 and are adapted to receive the rib 13 formed on thelocking bolt to prevent rotation or turning movement of the locking boltwhen the lockln end 1s disposed, Within the keeper.

slot 22 which prevents further rotation of the locking bolt. hen thelocking bolt is in this position, one end of the spring 14 engages thenotch 16 and prevents the bolt from being retracted, thus it will beseen that the door is firmly locked and that the seal cannot be removedwithout mutilating the same.

To unlock the door, the seal is broken and removed from the slot 11 andthe bolt 8 is then pushed further in the direction of the keeper 18until the rib 13 moves beyond the keeper and out of engagement with thenotch or slot 22 then the bolt 18 is rotated by the handle alining therib with the notch or slot 23 and then the bolt may be retracted as thenotch 18 is moved out of the path of the end of the spring 14.

A notch 24; is formed in the bolt 8 within the casing and angularly tothe notch 16 and has a straight shoulder which is disposed in anopposite direction from the straight shoulder 17 of the notch 18 andwhen the bolt is retracted, the notch passes beyond one end of thespring and if through accident the bolt 8 is moved in the directionofthe keeper with the rib 13 in alinement with the-slot or notch 23, theend of the spring engages the notch 24 or the straight shoulder thereofand prevents further movement of the bolt 8 in the direction of thekeeper, thereby obviating any danger of moving the bolt 8 into thekeeper with the rib in the wrong notch.

From the foregoing description, taken in connection with theaccompanying drawings, it will be noted that the necessity of usingtools for joining the ends of seals is entirely obviated as therailroad" company may furnish the various agencies with the endlessseals and said seals can be applied to the lock withoutthe employment ofa tool as is now customary.

While I have shown and described the preferred embodiment of myinvention, it will be understood that minor changes in construction,combination, and arrangement of parts may be made without departing fromthe spirit and scope of the invention as claimed. 7 i

Having thus described my invention what I claim is 1. In a lock, akeeper to receive an article for fastening, a turnable and slidablebolt, said keeper having an opening and notches in communicationtherewith a seal applicable to the bolt before extension into theopening of the keeper to limit its projection therethrough, a rib onsaid bolt to extend into either of the notches, means to hold the boltagainst rotation with the rib disposed in one of the notches, said boltbeing movable after removal of the seal out of one notch into the otherto permit retraction without interference by said means.
